SAN CLEMENTE – U.S. Border Patrol agents seized nine tons of marijuana from a truck at the 5 freeway checkpoint Thursday afternoon. Officials said the marijuana has a street value of more than $14 million.

Border Patrols agents stopped a truck with a 53-foot trailer at the checkpoint around 12:50 p.m. and asked the 43-year-old driver to move to a secondary search area, officials said.

Authorities said drug-sniffing dogs alerted officers to the trailer and when agents opened the door to the trailer, they found 218 cardboard boxes inside containing 18,458 pounds of marijuana.

Officials said the estimated street value of the marijuana seized is $14,766,448.
